METROPOLITAN SECTION PAPERS TREATMENT OF HYDROCARBON FUELS 170046

The author states that the objects of the paper are to define and trace the development of the various processes of carburetion, and to offer such suggestions along these lines as may assist the investigator in developing motorboats, automobiles and self-contained unit motor cars for railway purposes. The surface carburetor is mentioned chiefly as of historic interest. In considering the jet carbureter the author discusses the proportion of gas desired, the effect of the varying inertia of the air and the liquid gasoline and the breaking up of the combustible needed. Following sections review the devices for using kerosene, such as gasoline jet carbureters to which heat is applied, devices of the fixed gas type, the introduction of combustible directly into the cylinder, forcing combustible directly upon a hot surface in the cylinder and devices which raise the combustible to the boiling point. Under the section referring to the utilization of the heavy hydrocarbons, the various types of injectors used for this purpose by leading constructors of high-compression oil engines in this country and Europe are illustrated and the general subject is discussed. Two photographs of oil impinged upon paper illustrate the actual distribution of combustible in the jet issuing from the injector. In the concluding paragraphs the author refers to future automotive engines.
